How to Install Bolt-In Intermittent Wipers

If there’s one constant, it is change. While some change may not be for the better or may be out of our control, modern technology certainly helps change the way we enjoy our vintage Mustangs. It wasn’t that long ago that to enjoy something as simple as power windows in your Mustang meant fabricating your own mounts and using salvage yard motors and switches to make everything work. Today, you can simply bolt-in a ready-made conversion with compact motors and electronics that require no cutting to your door shell and give you the modern convenience you use every day in your other vehicles. Now you can do the same with another such modern convenience—intermittent wiper speeds.

The vintage Mustang’s wiper system is sorely lacking an intermittent speed function. For those who drive their vintage Mustangs on a regular basis and who realize their cars will not melt when hit with rain drops (we salute you!), having the added benefit of an intermittent speed function for those light rains that just don’t quite require low-speed operation is essential to driving safety. Constantly turning the wipers off and on manually during driving in light rain takes your eyes and concentration off of the road. While intermittent wiper upgrades have been craftily created with later-model Ford switch gear for other year Mustangs, the ’67-’68 Mustang’s wiper switch design in the face of the gauge cluster makes it all but impossible to mount something in the stock location—until now.

Enter Muscle Car Switch to the Mustang aftermarket. Muscle Car Switch engineers have taken their passion for vintage cars and their expertise in electronic circuit design to create their first direct bolt-in intermittent wiper switch. Thankfully, they chose the ’67-’68 Mustang as one of their first projects.

The Muscle Car Switch intermittent wiper switch features five intermittent speeds and retains traditional low- and high-speed wiper functions while maintaining the stock footprint of the OE switch. Except for a minor difference in the switch’s control lever, you’d never know that the Mustang is fitted with a Muscle Car Switch and now has intermittent wiper speeds!

Even better, with Muscle Car Switch’s optional automatic headlight controller, you can ensure your headlights come on when using your wipers (state law for many) while still maintaining full manual control of your headlights, including high-beam activation from the floor dimmer. The wiring involved is mostly “plug and play” with a couple of basic wire connections and the mounting of the relays. We felt the two products make the perfect pair for driver Mustangs and decided to add them to our friend’s ’68 Mustang hardtop.
